I last did this about 2 years ago and it did come up with my wallets with my BTC, which I have not looked at since.
The question is, given my 24 word code, is there any other way to use it to restor my wallet, or will it only work with bitstream green?
I guess I am asking if the 24 word code is proprietoary to this one wallet venord, or if other vendors support it too?
Recovery seeds will work on any wallets as long as it supports the seed type and it supports the seed so the problem lies elsewhere.
Are you sure that you entered the seed words exactly as it was? It has to be in the very same particular order or else you will get the different wallet and also you need to enter the Passphrase the extra word while creating the wallet if you used one in the past because the same seed will generate different set of private keys when you create with and without the Passphrase.
